This category brings together open investigative pieces on matters of public significance in Nizhny Novgorod. Among them are two independent investigations into the circumstances of Anna Stepanova's Removal from the Election): the Anna Stepanova's Removal from the Election (Kuznetsov's Investigation) and the Anna Stepanova's Removal from the Election (Iosilevich's Investigation), as well as a piece on the problems of SU-155 co-investors. Articles in this section are created as collective documents: any encyclopedia contributor can add new facts and sources to an investigation.
